Shaded rows are our picks. Assumed load: A CPAP with the humidifier and heated tube switched off, averaging 40W for an 8-hour night, run from the 12V socket with the maker's DC cable.
Why a BiPAP draws more than a CPAP
A CPAP blows air at one steady pressure. A BiPAP, short for bilevel, uses two: a higher pressure when you breathe in and a lower one when you breathe out. BiPAP settings often run higher than CPAP settings, and higher pressure means the blower works harder. Our numbers use a 60W average for a BiPAP against 40W for a CPAP, both with the humidifier and heated tube switched off.
Over 8 hours, 60W adds up to 480 watt-hours. A watt-hour is a unit of energy: one watt used for one hour. A CPAP night is 320Wh, so the BiPAP needs half as much again.
The second table on this page shows the gap. The Bluetti AC70 covers 2.2 CPAP nights but 1.4 BiPAP nights. A 1,000Wh unit drops from about 2.9 nights to 1.9.
Plan for your machine’s hard night
60W is a typical figure, not yours. Your pressure settings, how well the mask seals, and altitude all move the average. At 80W, every runtime in the table shrinks by a quarter. That is why the picks favor units with spare hours.
Use the maker’s DC cable
A power station stores DC power. Your BiPAP runs on DC too, and its wall brick only turns household AC into DC. Plug that brick into the station’s AC outlet and the power gets converted twice, with a loss each time. It is like paying a toll in both directions on the same road.
A DC cable from the car-style 12V socket skips both conversions. Our math gives the machine 90% of the battery over DC and 85% over AC, and the BiPAP table assumes DC. Buy the cable or converter that your machine’s maker sells for your exact model. A generic cable can drop voltage and shut the machine off.
The humidifier is not in these numbers
Heating water takes far more energy than moving air. On a CPAP, switching on the heated humidifier and heated tube roughly doubles the draw, from 40W to about 85W in our numbers. A BiPAP humidifier heats water the same way, so expect a large jump there too.
If you cannot sleep without it, treat the nights in the table as a ceiling and buy one size up. The CPAP humidifier guide shows how wide the gap gets.
UPS mode for the bedside
UPS stands for uninterruptible power supply. The station plugs into the wall, the machine plugs into the station, and the battery takes over when the grid fails. The gap is measured in milliseconds, which are thousandths of a second. A shorter gap gives the machine a better chance of carrying on without restarting.
The Bluetti Elite 100 V2 and Anker Solix C2000 Gen 2 list 10 ms. The Bluetti AC70 lists 20 ms. Jackery lists no figure for the Explorer 1000 v2. No maker promises that a given BiPAP will ride through the switch. Find out before you need it: with the machine running and you awake, unplug the station from the wall and watch what the machine does.
A note on medical need
BiPAP is often prescribed for more serious breathing conditions than a standard CPAP treats. If your doctor has told you that you must not go without it, a general-purpose power station is not the right safety net. Ask your equipment supplier about backup power made for your device. Treat this guide as sizing help, not medical advice.
The picks in detail
Bluetti Elite 100 V2
- 1.9 nights
- BiPAP, humidifier off
- 2.9 nights
- CPAP, humidifier off
- $489
- $0.48 per Wh
- 25 lb
- Weight
At 1,024Wh this covers 1.9 nights at 60W, so one night is safe even if your machine runs hard. At an 80W average it still gives about 11.5 hours. Left plugged in beside the bed, it switches to battery in 10 ms when the power fails. At $489 it is the lowest-priced 1,000Wh unit, and it refills to 80% in 45 minutes once the grid returns.
What fits
- 1.9 nights per charge with the humidifier off
- 10 ms UPS switchover
- $489, the lowest price in the 1,000Wh class
What does not
- Just short of two full nights at 60W
- 25 lb, 1.2 lb more than the Jackery Explorer 1000 v2
Sale prices under $400 have appeared.
Bluetti AC70
- 1.4 nights
- BiPAP, humidifier off
- 2.2 nights
- CPAP, humidifier off
- $359
- $0.47 per Wh
- 22.5 lb
- Weight
768Wh gives 11.5 hours at 60W, one full night with about 3.5 hours spare. That spare matters with a BiPAP. If your pressures push the average to 80W, the AC70 still lasts about 8.6 hours. At $359 it costs $130 less than the cheapest 1,000Wh unit. It will not cover a second night without a recharge, and its 20 ms switchover is slower than the 10 ms most models list.
What fits
- 11.5 hours at 60W, one night with margin
- $359, $130 less than the cheapest 1,000Wh unit
What does not
- 1.4 nights, so no second night without a recharge
- 20 ms UPS switchover

Jackery Explorer 1000 v2
- 2.0 nights
- BiPAP, humidifier off
- 3.0 nights
- CPAP, humidifier off
- $499
- $0.47 per Wh
- 23.8 lb
- Weight
This is the only unit under 2,000Wh that reaches two full nights: 16.1 hours at 60W. At 23.8 lb it is also the lightest of the four 1,000Wh models, which makes it the one to pack for a two-night trip with no hookups. Keep it for travel. Jackery's product page lists no UPS switchover time, and its 4,000 cycles are rated to 70% capacity, not 80%.
What fits
- 2.0 nights per charge with the humidifier off
- Lightest 1,000Wh unit at 23.8 lb
What does not
- No UPS switchover time listed
- Two nights with almost no margin at 60W
Jackery's list price is $559, and it has sold for less at other retailers. Jackery rates its 4,000 cycles to 70% capacity, not 80%.
Anker Solix C2000 Gen 2
- 3.8 nights
- BiPAP, humidifier off
- 5.8 nights
- CPAP, humidifier off
- $899.99
- $0.44 per Wh
- 41.7 lb
- Weight
3.8 nights on one charge, for storms that take the grid down for days. It lists a 10 ms switchover for bedside UPS use, and it refills fully from the wall in 58 minutes when power comes back. One expansion battery doubles it to 4,096Wh. At $899.99 it costs $0.44 per watt-hour, and at 41.7 lb it is not a travel unit.
What fits
- 3.8 nights per charge
- 10 ms UPS switchover
- Expandable to 4,096Wh with one expansion battery
What does not
- 41.7 lb
- About $21 more than the EcoFlow Delta 3 Max for the same 3.8 nights
Anker's list price is $1,499.99. Anker lists a 9W idle draw, which is low for this size.
Verdict
Buy the Bluetti Elite 100 V2 if the machine stays by your bed or you want one unit for home and short trips. Pick the Bluetti AC70 if one night at a time is enough and $359 is the budget. Take the Jackery Explorer 1000 v2 for two-night trips, but not for bedside UPS duty. Choose the Anker Solix C2000 Gen 2 if your outages last for days. Skip the 300Wh class. Half a night of BiPAP is not a plan.
How these numbers were worked out. Runtime = battery capacity × efficiency ÷ average watts. We use 85% efficiency for AC outlets and 90% for DC and USB ports, because some energy is lost as heat on the way out. A model is marked "can't run it" when the device needs more watts than the outlet gives, or a bigger startup surge than the unit is rated for. Your own device may draw more or less than our assumed load, so treat these as estimates. Prices were checked on 2026-10-04 and change often. Full method
